CDC Data Systems & Sources

CDC’s interactive, online database provides fatal and nonfatal injury, violent death, and cost of injury data.

CDC funds the National Violent Death Reporting System (NVDRS) in all 50 states, the District of Columbia, and Puerto Rico to gather, share, and link state-level data on violent deaths. NVDRS provides CDC and states with a more complete understanding of violent deaths. This enables policymakers and community leaders to make informed decisions about violence prevention programs, including those that address suicide.

NEISS-AIP provides nationally representative data about all types and causes of nonfatal injuries treated in United States hospital emergency departments. CDC uses NEISS-AIP data to generate national estimates of nonfatal injuries, including those related to self-harm.

CDC WONDER manages nearly 20 collections of public-use data for U.S. births, deaths, cancer diagnoses, tuberculosis cases, vaccinations, environmental exposures, and population estimates, among many other topics. These data collections are available as online databases, which provide public access to ad-hoc queries, summary statistics, maps, charts, and data extracts.

CDC’s YRBSS monitors health risk behaviors that contribute to the leading causes of death, disability, and social problems,  including suicide attempts and related behaviors, among 9th through 12th grade students in the United States.

NAMCS is designed to meet the need for objective, reliable information about the provision and use of ambulatory medical care services in the United States. Findings are based on a sample of visits to nonfederally employed office-based physicians who are primarily engaged in direct patient care and, starting in 2006, a separate sample of visits to community health centers.

NHAMCS is designed to collect data on the utilization and provision of ambulatory care services in hospital emergency and outpatient departments and ambulatory surgery locations. Findings are based on a national sample of visits to the emergency departments, outpatient departments, and ambulatory surgery locations of noninstitutional general and shortstay hospitals.
